Themes and objectives
LARME aims improving numerical methods for the simulation of renewable marine energy at large time and space scale. The vertical integrated models as well as the potential flow models are compared though the many scientific locks of this application :
- Multi-dimensional simulation: The first lock appears within the multi-dimensional simulations required for applications. If the previous works lead to satisfying results, they only consider one horizontal direction (in addition to the vertical integrated direction) [ Bosi18, Bosi19, Godlewski18, Godlewski21]. The implementation of the second horizontal direction significantly increase the complexity of the contact line between the buoy and the water and the number of degree of freedom in the motion of the buoy.
- Improvement of water dynamics: The vertical integrated model are particularly efficient for large scale simulations. However, some physical effects as the dispersion terms [ Chassagne19, Parisot19] and the description of the vertical profil of velocity in the water column [ Audusse11, Fernandez-Nieto18], are missing and can be essential for industrial applications. Eventually, submerged structures will also be of major interest for applications.
- Improvement of structure dynamics: In order to be used with various energy converter geometries, the numeric code must allow to take into account various efforts such as moorings [ Eskilsson06, Palm16, Palm20], connected pieces or flexible converters and collision of buoy.
- High-Performance Computing: When the final objective is the characterization of deployment sites under several meteorological scenarios or the optimization of converters, the efficiency of the numerical code is of crucial interest. This is why we keep in mind to develop a high order scheme with parallel computations, well-adapted preconditioner and coupling strategy will be considering to reduce the computational cost.
- Validation of the strategies: Last but not least, benchmarking with a numerical strategy well adapted to fluid/structure interactions will be carried out to validate our approaches.
